To all 'whom t may concern-f:

Be it knownthat l, PRESTON F. KURTEN- BACH, a citizen of the UnitedStates, residing at Brookings, in the county of,` Brookings and State ofSouth Dakota, have invented certain new and useful Improve-` ments inAttachments for Corn Pickers, of

which the following is a specification.

This invention has reference to .that class of agricultural machinesinwhich ears of 'corn are stripped from standing stalks as the machine 1sdrawn .over` the field, thel stalks being left standing and the earsbeing delivered toy a4 conveyor or 'chute through which they. travel toandover husking rolls `by which thehusksare vremoved andthe 'corn' thendeliveredl upon asecondyelevator or'conveyerfto be transferred toawagonor other vehicle for transportation towa place of storage oruse. Inthe operation' of these machines, it frequently happens that the ears'of corn are presented crosswise to the husking rolls so that',` thehusks arenot removed cleanlyffrom the ears and frequently choking of themachine results. It sometimes happens also that vpieceseof the stalksare broken ofll and travolto the husking rolls vwith the ears of corn,the husks and the pieces of stalks accumulating over the rolls yso thatthe machine m-ust be frequently stopped until the vobstruction can beremoved. These happenings cause delay in harvesting the cropanditherebyv add to the expense of operations'.` `,It is the object ofmy 4invention toprovide' an attachment which may be applied to any ofthe cornpicking machines now in use and the operation of which the earso fwcorn will be presented lengthwiseto lthehusking rolls and fedendwise over the.V same tothe delivery conveyer, and a further object ofthe invention is to provide means'whercby the husksand the hroken'piecesof stalk which may lbe present will be positively fed` vbe-` tween thehuskingrolls to drop upon the ground. 'The objects of my rinvention areattained in such a mechanism as. is illustrated in the accompanyingdrawings, and the invention resides incertain novel fea`r tures whichwill be hereinafter first fully described and theninore particularlypointed out in the appended claims.

In the drawings: Figure 1 is a front perspective view of my attachmentin operative position over the husking rolls; y f

Fig. 2 is a longitudinal sectionion the line 2-2 of Fig. 1, and

Fig. 3 is al transverse section on the line 3 3 of Fig. 2. i

In the drawings, the reference numeral v1 indicates a portion of theframe of the chute which forms a part of the corn-pick ing machine, and2 designates the cooperating husking 'rollers arrangedlongitudinallywithin the bottom of the chute. In carrying'out myinventioinl mount in the side railsy of the chute-near the upper endthereof a crank shaft 3 Vwhich is equipped at one endfwith asprocket 4'whereby it may *i be driven from-any convenient element of 3- arejournaled in boxes 6, to the lower sides 0f which are secured feederarms 7, and upon the shaft between thecranks thereofI ythe corn picker;The cranks of this shaft 'y secure disks 8, the peripheral edges ofwhich are preferably formed to present teeth or spurs 9. Upon the sideralsof the chute in'advance of the crank shaft, I secure short kposts orstandards 10 in which isfitted a front cross shaft .11, and upon thesaid shaft, alined withthe cranks 5 of the shaft 3, are secured brackets12 which project for-` clearly in Figs. 1 and 2. These brackets are eachprovided at one side with a collar or vwardly from the saidshaft `11, asshownv hub 13 encircling the shaft 11 and carrying a set` screw 14 whichis adapted to bear against the said shaft and thereby secure the *collarand the bracket in fixed position thereon. Fitted through an opening 15adjacentthe front end of each ybracket 12 is apin 16 having ahead 17 atits lower end which supports a yoke 18, as; shown. spring 19 iscoiled'aroundthe pin`16 "bes tween the bracket 12 and a washer 20 fittedupon the pin, a ycotter pin or similar retaining device 921 beingprovided at the upper extremity ofthe .holding pin 16 to prevent releaseof .the washerl or abut-k ment 20.

' ln the lower end of the yoke 18 is mounted a roller 22 having anannular groove 23 in llO above pairs of husking rolls, means forimparting longitudinal oscillatory movement to the arms, husk-engagingp-ins depending from the upper ends of the arms, and forwardly anddownwardly extending projections on the under side of the armsto engageears of corn disposed below the arms.

3. An apparatus for the purpose set forth comprising a crank shaft4adaptedr to be mounted in the side rails of a corn picker chute,husksengaging disks secured upon said shaft between the cranks thereof,feeder arms disposed longitudinally of the corn picker chute, means nearthe upper ends of said arms to suspendv the same on the cranks of saidcrank shaft, andmeans for supporting the lower ends of the feeder armsand permitting longitudinal oscillatory move-.

ment of the same in orbital paths.

4. An apparatus for the purpose set forth comprising feeder arms,brackets disposed above the said arms near the forward ends thereof,rollers carried by said brackets,l supporting guides secured to thefeeder arms f therefrom to pass through and adjacent the front endsthereof and extend ing upwardly and rearwardly*therefrom to pass overthe said rollers, and means for supportingthe rear ends of the feederarms and imparting, longitudinal oscillatory movement thereto.

5. An apparatus for the purpose set forth comprising feeder arms, acrank shaft,

means upon the arms adjacent the upper ends thereof to suspend the armson the cranks of said shaft, a shaft disposed above the arms adjacentthe forward ends thereof,

brackets secured u on and aro'eetin' for# `wardly from said shaft,`yieldably supported pins carried by said brackets, yokes carried by theylower ends of said pins, and guides secured upon the arms at the frontends thereof and rising upwardly and rearwardly .be supported in saidyokes. f i
